can you compost the toxic parts of the plant for use in other parts of garden?

Probably ok to compost.

We have very recently (April) moved some rhubarb plants that originated from my FIL's family homestead many years ago, from Denver CO to SC. I desperately want to keep these alive, mostly for my husband. Any advice? Our ground is hard as a rock in most spots and has a lot of clay, so figured I need to keep them in pots. How big of a pot do I need, should I be sure to put them on the side of the house where there's mostly only morning sun, in order to continue the "family line", should I try and gather seeds from the plant for the following year? Thanks!

you really are better off putting them in a raised garden bed with mixed clean top soil, lots of compost, peat moss, blood meal, and a slow release fertilizer. Rhubarb get very large and can live for many years and their root systems can get quite large, keeping them in pots will restrict their growth and you will have to water more often and continually use fertilizer more often then them being in the ground.

I suggest you read some articles about growing them. The bigger the pot the better 18-24

Is rhubarb ready to eat when the stalks are still green? Our plant is a few months old.
